Code Classification

  • Diseases of the musculoskeletal system and connective tissue
    (M00–M99)
    • Systemic connective tissue disorders
      (M30-M36)
      • Systemic disorders of connective tissue in diseases classified elsewhere
        (M36)

M36 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of systemic disorders of connective tissue in diseases classified elsewhere. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Systemic disorders of conn tiss in diseases classd elswhr

Non-specific codes like M36 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for systemic disorders of conn tiss in diseases classd elswhr:

  • Use M36.0 for Dermato(poly)myositis in neoplastic disease - BILLABLE CODE

  • Use M36.1 for Arthropathy in neoplastic disease - BILLABLE CODE

  • Use M36.2 for Hemophilic arthropathy - BILLABLE CODE

  • Use M36.3 for Arthropathy in other blood disorders - BILLABLE CODE

  • Use M36.4 for Arthropathy in hypersensitivity reactions classified elsewhere - BILLABLE CODE

  • Use M36.8 for Systemic disorders of connective tissue in other diseases classified elsewhere - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Patient Education


Connective Tissue Disorders

Your connective tissue supports many different parts of your body, such as your skin, eyes, and heart. It is like a "cellular glue" that gives your body parts their shape and helps keep them strong. It also helps some of your tissues do their work. It is made of many kinds of proteins. Cartilage and fat are types of connective tissue.

Over 200 disorders that impact connective tissue. There are different types:

  • Genetic disorders, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta
  • Autoimmune disorders, such as lupus and scleroderma
  • Cancers, like some types of soft tissue sarcoma

Each disorder has its own symptoms and needs different treatment.
